Homebrew games and applications sometimes don't have to be extravagant and complicated - these things only come second to being fun and usability. One such application is homebrew developer waywardson's PSPGraph that was released over at QJ.NET PSP Development Forum.

Basically, this application allows users to plot a line on a graph. We imagine that some of you may find this useful especially during Geometry classes if only to give you an excuse to bring out your PlayStation Portable units. You can plot a line by assigning values to the X and Y axes of both points.

PSPGraph doesn't come with a Readme.txt file but everything you need to know including the keymap are printed on the application's main screen.
